Join the 400th Engadget HD Podcast live on Ustream at 9:30PM ET

Listen to the Engadget Mobile Podcast, live at 4PM ET!

Just because there are a few celebrations going on this time of year, doesn't mean mobile news stops coming -- for one, AT&T lobbyists and lawyers are getting some well-deserved time off for the holidays! So in honor of the season, we feel like getting a little jolly today and are ready to crank out a podcast for all the world to hear. So join Myriam and Brad -- and our very own Richard Lai -- for a special holiday episode of the Engadget Mobile Podcast today at 4PM ET!

Note: The recorded podcast will likely not be available for download until after the weekend. All the more reason to join us today for the livecast!
